REPAIRING frmn-cAsINGs.

Specification of Letters Patent. Patented A1113 12, 11921.y

Application filed April k25, 1919. Serial No. 292,537.

T0 all who/m, it may concern:

Beit known that I, FREDERICK I), Goon- LAnn, a citizen of the United States, residing at West Palm Beach, in the county of Palm Beach and State of Florida, have invented new and useful Improvements in Repairing TireeCasings, of which the following is a specification. Y

The object of my invention is the provision of simple and easily applied means for effectually repairing in a practical, durable and finished manner rim cuts '1n tire casings.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part hereof Figure 1 is a side elevation showing a portion of a tire casing equippedwith my novel means for repairing rim cuts.

Fig. 2 is an enlarged, transverse section taken in the plane indicated by the line 2-2 of Fig. 1 and showing my improvement in detail.

Similar numerals of reference designate corresponding parts in both views of Vthe drawings.

My novel means for repairing rim cut casings is applicable to clencher or straight side casings, and if it be assumed that a casing side is cut to the extent indicated by the heavy dotted line 1 in Fig. 1, my improvement will be readily understood from the following detailed description;

I proceed rst by cutting away the rubber layer 2 of the casing along the lines 3 and 4. I then apply para or other suitable cement'to the side as indicatedby 5 in Fig. 2, after which I applyto the side in straddling relation a layer 6 of strong textile material. rIlhis layer 6 is of less area than that described by the cuts 3 and 4 in about the proportion illustrated. I then apply a layer 7 of para or other suitable cement to the exposed side of the layer 6. Against the said cement layer 7 I arrange 'a layer 8 of strong textile material, this layer 8 being slightly larger in area than the layer 6 in about the proportion illustrated. To the exposed side of the layer 8 I apply a layer 9 of para or other suitable cement, and against said layer 9 I arrange a third layer 10 of strong textile material, which layer 10 is larger in area than the layer 9 in about the proportion illustrated. 'The layers ofy strongv textile material are inthe ends and side edges of the vrepair means.

Any suitable number of textile layers may l be embraced in the repair means in the discretion of the repair man, three layers 6, 8 and 10 being preferably employed in the larger and heavier casings. Over the outermost textile layer 1() I arrange a layer 11 of dry-tanned leather-z'- e., leather that is free from oil or grease, and I alsov interpose a layer 12 of ara or other suitable-cement between the ayer 10 and the leather layer 11. The said leather layer 11 is arranged with its rough or flesh side inwardly, in order to assure secure holding of the layer by the cement as well as to enable the finished side of the leather layer to enhance the finished appearance of the repair when the same is completed. kIt will be readily apparent from Fig. 1 that the leather layer 11 is of an area to fully occupy the spacer Yformed in the rubber layer ofthe casing by the cuts 3 and 4; also, that ay portion of the leather la er 1l is arranged flush with the surface o the rubber layer of the casing. After the application `of all of the layers in the manner described, the saidk are connected together and to the layers casing side 13, Fig. 2, through the medium of a plurality of through and through transverse rivets 14, the heads 15 of which are arranged substantially flush with the exposed side of the leather layer 11 as illustrated. To complete the repair, I arrange at the inner slde of thecasing side 13 'and in such manner as to cover they inner heads of all of the rivets 14, a layerr15 of soft textile or other fabric which is preferably, though Vnot necessarily, secured by cement to the adjacent portion of the leather layer -11 andhas for its function to prevent the inner headsof the rivets 14 fromV chafing the inner tube of the tire. f

. When effected in the manner described,

ilov

my novel repair for a rim cutV casing will last quite as long as the remainder of the casing, and hence willrprolong the usefulness of the casing as a whole, whichfwill be appreciated as a highly important advantage when'the cost of tire casings, particularly large casings, is taken into consideration. It will `also be manifest that my novel repair may be expeditiously and easily eiected without resorting to -vulcanization,

and it does not detract in any measure from the nished appearance of the casing.

Having described my invention, What I claim and desire to secure by Letters-Patent, is:

A repaired rim-cut tire casing comprisq ing the casing side portion from which an area of the outer rubber layer has been removed, a plurality of textile layers straddling said portion, interposed cement layers connecting said textile layers together and to the casing,` side portion; the inner textile layer being smaller in area than the cut removed portion in the casing side and the other textile layers being increased in area as they recede from the casing side portion to afford feather edges at tne ends and side edges of the repair means9 an outer leather layer straddling and cemented to the outer textile layer and arranged with its flesh side inwardly and its smooth side outwardly and also arranged Hush with the surface of: the outer rubber layer of the casing and fully occupying all of tlie'space left by the said removal of a portion of said rubber layer, and rivets extending` transversely through and joining the said casing` side portion, the textile layers and the leather layer.

In testimony whereof l my signature.

FREDERICK D. GOODLAKE.
